i Application led December 2l, 1906. Serial No. 348,869.

To all whom it may concern? Be it known that I, .Toi-1N B. Monnow, a 'citizen of `Paper-Coating Machines, oi which the following is a specification. i

The brush-holder which is the subject or' this invention is or holding the flat brush which spreads the color, in distinction from rotary brushes which apply the color and are usually' round.

Much time is now lost in machines ot the character rei'erred to in removing the flat brushes, as for cleaning purposes because the said brushes have been rigidly attached to the underside of the piece on which they are supported. These brushes vibrate horizontally and longitudinally several times a second, and it has been necessary to stop the machine in order to remove them and return or replace them.

This invention has for its object to provide a brushholder which will allow the brush to be removed and applied or replaced without stopping or slowing down l accomplish this desirable object by making ,the support for the brush in the form ot a trame or holder which is open in its center tor a space large enough to permit the bristle portieri of the brush employed to pass through and by providing suitable means, such as a spring lock, tor securing the brush Vto the raine. When it is desired to remove the brush, it is only necessary to release the brush from the lock and lift it out 'of the trarne or holder. This may be done very easily and without stopping the machine.

The nature ot the invention is ully described below, and illustrated in the accompanying drawings, in vvliichz-c Figure l is a plan view oi my improved brush-holder with the brush in position therein, the central portion being broken out and the brush represented being supposed to be about forty inches or more long and about 'l our and one-halt inches wide. Fig. 2 is a section taken ou line 2-2, Fig. l, dotted lines showing the brush being removed. Fig. 3 is an end elevation looking toward the right, Fig. 4 is a section taken on line 4 4, Fig. l looking toward the lelt.

Similar letters of yreference indicate corresponding parts.

a represents a flat brush for spreading the color, constructed substantially as usual.

b is one of the metallic ends o the holder provided with the ordinary outwardly extending rods c which are connected with the power whereby the brush is vibrated longitudinally. This end-wall b has its upper portion thickened at b and provided on its under surface with a washerA or elastic cushion d, The opposite ends oi the lower portion of the end-wall b are provided i Specification of Letters Patent.

with the inwardly projecting parallel extensions e, said extensions being formed ,on their outer surfaces, with horizontal parallel sockets g in which the right ends of the usual connecting rods 7L are heldby said screws g.

lc represents the opposite end-wall, whose lower portion is provided with inwardly projecting extensions similar to the extensions c and provided with horizontal parallel sockets l exactly like the sockets'g, wherein the lett ends of the rods hare secured by set-screws Z. The upper portion ot the end-wall k is thickened at k outwardly, that is, toward the left, instead of inwardly toward the right as with the end-wall b. The portion lc sustains the ordinary outwardly extending rods m exactly like the rods c, connecting with the power, all the rods m and r: being held rigidly in position by suitable set-screws n. The lower edge oi the end-wall lc is provided with an inwardly extending horizontal shelf o, and a cross-bar q t Fig. 2) extends from one oi the extensions e to the other, said extensions being provided on their inner sides with horizontal flanges e-the said shelr1 o, cross-bar q and lianges e being on the same plane and supporting the back of the brush a.

The end walls l) and la with their inwardly projecting extensions e and f, the side connecting rods h, the horizontal shelf o and cross bar q together form the trame or holder for the brush a, the bristles of the said brush projecting through the opening in the center ot the trarne or holder. The portion c of the endwall k is horizontally bored at p to receive a bolt s provided at its inner end with a latch t set vertically and with its beveled or rounded edge t extending upward. This latch is held normally with its iiat lower end over the left edge or' the brush a by a spring Iv whose lower end is secured at 1/ to the `end-wall lc, and whose upper end is bent outward and upward against the outer end of the bolt s. The brush is therefore held in position in the holder, resting on the portions o, q'and ef, and overlapped at one end by the elastic washer d and at the other end by the latch t. When it is desired to remove the brush the latch t is pressed back by the hand oi the operator and the brush swung up and lifted out while the holder is vibrating at its regular speed, such speed never being so great as to prevent the hand of .the operator from vibrating with it as he is working the latch and removing the brush, swinging it up as indicated in dotted lines in Fig. 2. i

Having thus fully described my 1nvent1on, what 1 claim and desire to secure by Letters-Patent, is:-

1. A brush holder for paper coating machines consisting or' a frame having an opening therethrough, combined with a brush the back of which extends beyond the bristle-holding portion thereof so that the bristles may project through the lower side of said opening with portions of the back oi the brush resting upon underlapping portions of said frame, and a spring catch or latch engaging said body portion of said brush when the latter is seated in said frame whereby said brush is adapted to be detachably secured to said frame in such a manner that it may be quickly removed therefrom through the upper side of said opening.

2. A brush holder for paper coating machines consisting of a frame having an opening therethrough, and having outwardly extending end rods by which it may be reciprocated, combined with a brush the back of which extends beyond the bristle-holding portion thereof so that the bristles may project through the lower side of said opening with portions of the back of the brush resting upon underlapping portions of said frame, and a spring catch or latchv engaging said body portion of said brush when the latter' is seated in said frame; whereby said brush is adapted to be detachably secured to said frame Ain such a manner that it may be quickly removed therefrom through .the upper side of said opening.

3. A brush holder for paper coatingmachines consisting of a frame having an opening therethrough, with brushsupporting or shelf portions at or near the ends of said opening, combined with a brush the back of which extends beyond the bristle-holding portion thereof so that the bristles may project through the lower side of said opening with portions of the back resting upon the said brushsupporting or shelf portions of said frame,` and a spring catch or latch engaging said body portion of the said brush when the latter is seated in said frame; whereby said brush is adapted to be detachably secured to said frame in such a manner that it may be quickly removed therefrom through the upper side of said opening.

4. In a paper coating machine, the combination of a flat brush having portions of its back projecting beyond its bristle portion, a movable frame or holder therefor having a central opening therethrough for the reception of the bristle portion ofthe said brush, said holder comprising end walls, one of which is provided with a socket at one end of said opening for the reception of a projecting pornon of the brush back, and another of which, at the other end of said opening in said frame or holder, has a portion on which another projecting portion of the brush back rests, with the bristles of the brush projecting below, and spring-operated locking means for securing the free end of the brush back in place and permitting of its quick removal from the upper side of said frame or holder.

5. In a papery coating machine, the combination of a flat,

brush having portions of its back projecting,r beyond its bristle portion, a movable holder therefor having a central opening therethrough for the receptionof the bristle portion of the saidbrush, means extending inwardly from one end of said central opening for'the reception of a project ing portion of the brush back, and engaging mechanism at the` other end of said central opening, in normal engagement with the brush, but capable of being withdrawn from such engagement, whereby the brush may be removed from the holder without stopping the machine. v

G. In a paper coating machine, the combination ofa fiat brush having portions of its back projecting beyond its bristle portion, a movable holder therefor having a central opening therethrough for the reception of the bristle portion of the said brush, an inward extension from one end wall of the said opening adapted to overlap one end of the brush, supporting means ntegral'with the said holder for supporting and under-lapping the brush, a bolt sliding in the end wall opposite that which is provided with the inward extension, a, latch supported by the inner end of the said bolt, and a spring holding said latch normally over rthe end of the brush.

In testimony whereof 'I have signed my name to this specification in the presence of two subscribing witnesses.
